Reasons for Excessive Engine Oil Pressure?
1 Answers
Reasons for excessive engine oil pressure include: 1. Low oil viscosity; 2. Clogged oil pickup screen or oil filter element; 3. Weakened or broken pressure relief valve or return valve spring, leading to poor valve sealing; 4. Excessive clearance in main bearings or connecting rod bearings; 5. Poor oil pump performance. Methods for checking engine oil pressure: 1. Inspect the oil pressure gauge and sensor, replacing them if malfunctioning; 2. Verify oil viscosity meets specifications, replacing with appropriate viscosity oil if too high; 3. Adjust the pressure relief valve to ensure oil pressure meets requirements; 4. Regularly clean oil lines, passages, and maintain the filter.
